After saying that, I looked at it and put it in my mouth and swallowed it!

After a while, this time the feeling was not much different from the last time when the blood wolf devoured the inner dan, it was all part of the essence entering the dantian, expanding the space of the dantian and increasing the depth of the true qi.

The other part also flows into the bones for transformation, "crackles~crackles~"

Another crackling sound came from the bones, and the whole body felt numb.

Immediately after that, a large amount of Neidan essence began to drill into the bones, and the slight difference from the last time was that this time the Neidan essence did not completely flow into the bones, but a lot of essence flowed into the joints of the body.

At this time, there was a tingling sensation in the joints, as if it was softened by this essence, so that Feng Langxing couldn't help but want to scratch, and the feeling of numbness kept coming from all over the joints、、、 and finally after half an hour, this feeling gradually weakened, and at this time, the essence of Neidan had completely entered the body, and the transformation of the bones was basically completed.

A large amount of surplus essence began to flow from the bones to the flesh and through the flesh to the skin.

A new round of transformation began, and this time the skin and flesh were not getting tighter and harder like last time, but as if they had been softened by this essence, they became soft and weak!

The sudden change made Feng Langxing start to worry, the sturdy defense that had been cultivated after so long of strengthening had been softened like this, could it be that all the efforts for so long were in vain?

The wind and waves did not stop immediately, but quietly observed, and finally after half an hour, all the changes stopped.

Feng Langxing immediately stopped, touching the skin and flesh that had become extremely soft, his eyes were full of chagrin and doubt, and he secretly thought: "Could it be that Neidan's transformed body will go backwards?"

Pinching the soft flesh on his arm, the teeth of the wind and waves creaking, and his face was full of distress!

After thinking for a moment, he said, "Let's see what this change is first," and then picked up the Flame Separation Sword and prepared to experiment on it in his hand first.

As the fire sword slashed from his fingers, Feng Langxing obviously felt a tingling pain, and he felt bad at that time, and secretly cried and laughed: "This time I really lost my wife and broke my soldiers!"

Almost disappointed, he looked at his "bleeding" finger, and then said with some surprise: "Huh, there is no bleeding, is my force too small?"

Then he used the fire sword to cut his fingers, this time Feng Langxing deliberately used some strength, and the fire sword slashed silently again, and the same pain came again, but there was still no blood.

Feng Langxing looked at the fingers that were still not bleeding, and the disappointment on his face just now had disappeared, replaced by surprise and curiosity.

Holding the fire sword again, he cut it into his palm, and this time Feng Langxing used a lot of strength, so he cut it, if it was cut on a punch-thick wood, the wood would undoubtedly be cut into two pieces, and Feng Langxing wanted to see how much force his weak palm could withstand the cutting.

Similarly, although Feng Lang Xing's hand felt pain, it did not even break a layer of skin, it was still soft and ruddy, and Feng Lang Xing was immediately shocked.

It seems that the hand that looks extremely weak can withstand such a sharp sword from the fire, as if it is far from the limit.

Feng Lang Xing began to increase his strength to try to measure his current defense limit, until Feng Lang Xing used the greatest brute force of his body to swing the fire sword and slash at his left hand, but there was still no trace of it, although Feng Lang Xing would make himself feel pain every time he cut his hand, but he couldn't hurt it, and even his skin didn't hurt, which undoubtedly made Feng Lang Xing excited, and it also made him more eager to understand the limit of his body's current defense.

Feng Lang Xing poured the true qi into the fire sword for the first time to test, after the true qi was infused, the sword body that was red from the fire sword exuded a strong heat, waving it, swinging it hard and cutting it on the palm, Feng Lang Xing could feel the heat from the sword body, making Feng Lang Xing have a feeling of being burned by fire!

After the blade was slashed, and when I looked at my left hand, a red line finally appeared on my left hand, but after a few moments it disappeared again.

This time, even if it is a demon beast with five hundred years of cultivation, it can draw a mark, leaving a red mark on his hand that disappeared after only a moment, Feng Langxing once again injected more true qi into the fire sword, and slashed at his left hand, "呲呲~"

After a sound of knife palm rubbing, the skin on the left hand, which had been tenacious, was cut open, leaving a white line in the soft palm, but this time it did not disappear again, and a trace of blood slowly flowed out.

The strength used by Feng Langxing this time can definitely easily cut a hole in the skin of a five-hundred-year-old demon beast, of course, it is a demon beast with weaker defense, even so, his current defense power can definitely match the level of an ordinary five-hundred-year-old demon beast.

Feeling the strong defense of the whole body, Feng Langxing can be sure that when he fights the five-hundred-year-old demon beast now, he will definitely win, and he will not return with a serious injury like the previous two times.

"Whoop~"

Feng Langxing almost cried out excitedly, and his feet tapped a few times on the stone wall of the cave, leaving a series of afterimages in the cave, venting his excitement at the moment.

I don't know if it's because I'm too excited or because I feel particularly good today, Feng Langxing feels that his steps are more handy, and his perception of the wind seems to be more profound!

After a while, Feng Langxing found a reason for himself - in the battle with the twin-tailed cat, his own sense of wind and wind became more profound.

I don't think much about the wind and waves.

After testing the body's defense, Feng Langxing couldn't bear to get more demon beast Neidan's **!

Because Neidan has helped him too much, this may be the glimmer of life for him to pass this test, otherwise relying on his slow cultivation speed alone, it is almost impossible to kill a thousand-year-old demon beast even in five years, let alone a full hundred!

Thinking that with the help of Nedan, he still killed two five-hundred-year-old demon beasts with great difficulty, if he didn't rely on Nedan's help, he might have been destroyed when he fought with the five-hundred-year-old demon beast for the first time, and it seemed that he could grow to the point of killing thousand-year-old demon beasts in three years, and Nedan's help was absolutely indispensable.

Finally, the wind and waves are heading for the forest again!

Advancing quickly towards the depths of the forest, the smile on his face could no longer be hidden, and he still muttered a sentence in his mouth: "The value of the birth of these demon beasts is to make me stronger faster, hum, Neidan will hand it over to me!"

When passing through the territory of the blood wolf and the twin-tailed cat, Feng Lang Xing deliberately slowed down his pace, for these two demon beasts, Feng Lang Xing still paid special attention, two battles, not only let Feng Lang Xing return with serious injuries, but also made him make rapid progress twice, so that Feng Lang Xing continued to improve himself.

After slowing down, he was surprised to find that there were many five-hundred-year-old demon beasts wandering nearby.

However, few dared to venture into the interior, let alone be the king of exclusivity, so Feng Langxing felt that this area was particularly special.
